Your caravan has been fitted with a PROTECTOR alarm system. This provides comprehensive protection for your caravan, when parked or coupled to your tow vehicle, as well as protecting the contents. The alarm system is controlled by a key fob, which can also switch the awning light on/off. When the alarm is on, pressing both fob buttons sounds the siren (PANIC ALARM). If you insure with the Caravan Club, K.Drewe (Insurance) or CARAVAN GUARD Insurance you should be eligible for a discount on your premiums.

The alarm system is simple to use, full instructions are given in the section USING YOUR ALARM. A product specification is given at the end of these instructions.


The caravan must be fitted with a 12 Volt leisure battery for the alarm system to work.

The key switch on the control box should have been left in the  clockwise position, otherwise the alarm will not work.


Press the ALARM button on the key fob for a couple of seconds to switch the alarm on. The siren will “cheep” twice so you know that the alarm has been activated. Should a thief trigger the alarm the siren will sound for 2 minutes and reset. On your return switch the alarm off by pressing the ALARM button on your key fob for a couple of seconds. The siren will “cheep” once so you know the alarm has been de-activated.

When using the alarm with the caravan coupled to your tow vehicle (for example at motorway service areas) remember to switch the alarm off on your return, otherwise the first time you use the foot brake you will  trigger the alarm siren.

To switch the awning light on/off press the LIGHT button on the key fob. (Please note that this light must be switched on with its own switch before it can be switched off then back on using the key fob.)


Once you  have switched the alarm on and the siren has “cheeped” twice, any one of the following actions will trigger the siren for 2 minutes or until the alarm is switched off :-



Anti Theft Alarm 1  Sensor fitted to rear leg

Anti Theft Alarm 2  Insertion or withdrawal of 13 pin (or 12N) plug when coupled up

Anti Theft Alarm 3  Foot brake operation with 13 pin (or 12N)plug inserted

Note - we recommend charging leisure batteries every 2 months


The diagnostics LED on the control box is intended for Dealer use. This red LED indicates which sensor has triggered the alarm. Reset by switching key switch off then back on again after noting the number of flashes. Flash codes are :-

Regular flashes = Alarm ON

1 flash = Panic     

2 flashes = Leg Sensor,

3 flashes = PIR,

4 flashes = 12N plug

5 flashes = Leisure Battery disconnected
